NEW HORIZONS IN RENTAL KART

Viper E-Kart

Boasting unmatched performance within its sector and the capability for autonomous driving sessions lasting over one hour when needed, the Viper E-Kart, the inaugural electric kart introduced by OTK Kart Group, signifies a groundbreaking transformation in the realm of rental karting. Viper E-Kart combines the latest lithium battery technology with easy maintenance for all operators, guaranteeing an exciting driving experience for all drivers (minimum 13 years old/140 cm tall) and safety standards that protect both customers and business

THE MOTOR

THE ELECTRIC BY OTK KART GROUP

Viper E-Kart is equipped with an electric motor (brushless permanent magnet motor), developed and created specifically for karting, which guarantees a nominal power of 5.5 kW (peak of 12 kW) and an exceptional peak torque of 145 Nm at the wheels (45 Nm at the crankshaft). Its low weight of approximately 197 kg allows the electric rental kart by OTK Kart Group to be the benchmark product in the kart rental sector, for performance and reliability (why? Find out on the "Safety" page).

Icona più Practical advantages

Zeroing of CO2 emissions (and other gases harmful to humans and the environment) and noise emissions.
Access (depending on country) to tax breaks and bonuses for sustainable start-ups.
Streamlining of bureaucratic procedures for obtaining authorizations relating to the opening (and ordinary management) of outdoor and indoor kart tracks.
Reduced maintenance, thanks to the fewer moving mechanical parts with which they are equipped.

WEIGHT OPTIMIZATION

BATTERIES LASTING OVER 1H, WITH OPTIMIZED CHARGING TIMES

The electric motor of the Viper E-Kart is powered by 116 Ah NCM lithium batteries, a capacity at the top of the rental kart sector. This quality, together with the optimized weight of 197 kg, makes the Viper E-Kart the electric rental kart with the best “capacity/weight” ratio available on the market, 0.589 Ah/kg. This means that for every kilogram of weight, the kart provides almost 0.589 Ampere/hour of battery capacity. Concretely, Viper E-Kart offers the best energy storage efficiency and driving times of over an hour per charging cycle.

Regarding the charging station and the necessary timing:

7 kW three-phase chargers are required. Specifically supplied by OTK Kart Group, they communicate via CAN with the battery control unit, ensuring optimized charging times and greater longevity of the batteries themselves
The time ratio between charging and driving is 1 to 1. This means that 20 minutes of charging corresponds to approximately 20 minutes on the track.
